Publication number: 20260064185Abstract: The present disclosure describes programmable logic that may be operated in a turbo processing mode to cause an ongoing operation to be completed faster than a scheduled completion time. With at least some of the remaining time to the scheduled completion time, power savings may be realized by operating the programmable logic into a deep sleep mode, where configuration memory associated with the programmable logic may be set to a suitable voltage level as to not cause data loss at lower or zero voltage levels but otherwise realize power savings relative to an amount of power consumed during average processing operations.Type: ApplicationFiled: November 11, 2025Publication date: March 5, 2026Inventors: Mahesh K. Kumashikar, Ankireddy Nalamalpu, Mahesh A. Iyer, Atul Maheshwari, Yuet Li, MD Altaf Hossain

Patent number: 12437135Abstract: Systems or methods of the present disclosure may provide for determining a loadline for operation of a programmable logic fabric where the loadline is based at least in part on design configuration details for a design or a configuration rather for generic deployment of the programmable logic device. The loadline may be determined using software modeling for the design or configuration. Additionally or alternatively, the loadline may be determined using runtime testing and sensing of real-world parameters. This determination based on real-world parameters of a deployment of the configuration or design is based on a determination of a step load for the design or configuration.Type: GrantFiled: December 22, 2021Date of Patent: October 7, 2025Assignee: Altera CorporationInventors: Yuet Li, Ankireddy Nalamalpu, Atul Maheshwari, Md Altaf Hossain, Mahesh K.

Patent number: 12273107Abstract: Embodiments of the present disclosure are related to dynamically adjusting a timing and/or power model for a programmable logic device. In particular, the present disclosure is directed to adjusting a timing and/or power model of the programmable logic device that operates at a voltage level that is not other than a predefined voltage defined by a voltage library. A system of the present disclosure may interpolate between voltage levels defined by the voltage libraries to generate a new voltage library for the programmable logic device. A timing and/or power model may be generated for the programmable logic device based on the new voltage library and the programmable logic device may be analyzed using the timing and/or power model at the interpolated voltage. The timing and/or power model may be used to generate a bitstream that is used to program the integrated circuit.Type: GrantFiled: December 22, 2021Date of Patent: April 8, 2025Assignee: Altera CorporationInventors: Atul Maheshwari, Mahesh Iyer, Mahesh K.
